Abstract

The invention discloses a filter tank, which relates to the technical field of water treatment, in particular to a filter tank with an annular filter assembly. The filter tank aims at the problems that an existing filter tank is large in occupancy, large in backflushing water using amount and complex in operation and cannot meet requirements of middle and large water treatment equipment. The filter tank comprises a casing, the annular filter assembly, a backflushing assembly and a rotary mechanism, wherein a raw water inlet pipe and a clean water outlet pipe are arranged at the bottom of the casing, the annular filter assembly is arranged in the casing, the backflushing assembly is matched with the annular filter assembly, the rotary mechanism is connected with the backflushing assembly to be driven to rotate, the raw water inlet pipe is communicated with an inner cavity of the casing, an inner cavity of the annular filter assembly is communicated with the clean water outlet pipe to be used for filter raw water in the casing into clean water to be outputted from the clean water outlet pipe, and the backflushing assembly is used for washing the annular filter assembly and exhausting slurry out of the filter tank. The filter tank is especially applied to efficient filter equipment in small and medium water treatment projects.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter tank with an annular filter assembly. Background technique [0002] In the field of solid-liquid separation, in addition to sedimentation and air flotation technology, filtration plays a very important role. Since the appearance of ordinary fast filters at the beginning of the last century, there have been siphon filters that do not need to store flushing water, valveless filters that do not need to switch multiple gates, and air-water reaction that saves flushing water and improves flushing effects in recent years. These changes and improvements have improved the technical level of filtration, but there are still some insurmountable obstacles that affect the further development of filtration technology. [0003] For example: the use of traditional granular filter materials cannot achieve reverse particle size grading; even for homogeneous filter materials, afte...
